It's still 1013.2 Danny. I've no idea why the RAF still use QFE either.
Don't know how transition levels et al were defined in your day but these days transition altitude is the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes. Transition level is the lowest flight level available for use above the transition altitude and the transition layer is the airspace between the transition altitude and the transition level.
The other thing we need in the UK is a common transition level, one that is preferably above our highest mountains...
